Cell migration involves dynamic and spatially regulated changes to the cytoskeleton and cell
adhesion. The Rho GTPases play key roles in coordinating the cellular responses required …

INTRODUCTION The plant root grows indeterminately. Continual birth and maturation of
cells in a gradient along the root longitudinal axis requires tissue-wide coordination of cell …

Small GTP-binding proteins regulate diverse processes in eukaryotic cells such as signal
transduction, cell proliferation, cytoskeletal organization, and intracellular membrane …

Root hairs provide a model system for the study of cell polarity. We examined the possibility
that one or more members of the distinct plant subfamily of RHO monomeric GTPases …

Small GTPases, having masses of 21 to 30 kD, are monomeric guanine nucleotide binding
proteins related to the subunit of heterotrimeric G proteins. All small GTPases belong to a …

T and RIC4. RIC4 promotes F-actin assembly, whereas RIC3 activates Ca2 signaling that
leads to F-actin disassembly. Overproduction or depletion of either RIC4 or RIC3 causes tip …

The plant-specific Rop family GTPases are versatile molecular switches in many processes
during plant growth, development, and responses to the environment. To understand how …

The regulation of cell differentiation at meristems is crucial to developmental patterning in
plants. Rapid progress has been made in identifying the genes that regulate differentiation …

RAC/ROP GTPases are a family of plant-specific signaling molecules solely representing
the Ras and Rho family of Ras-related G proteins in plants. RAC/ROPs potentially interact …
